Manufacture And Characterization Of Lightweight Brick Using Sinabung Volcanic Ash And Pinang Fiber As An Aggregate With Polyester Adhesive
Manufacture and Characterization of Lightweight Brick Using Sinabung Volcanic Ash and Pinang Fiber as an Aggregate with Polyester Adhesive
Introduction
The construction industry has been facing a significant challenge in recent years, with the increasing demand for sustainable and environmentally friendly building materials. One of the most promising alternatives to traditional building materials is the use of lightweight bricks made from locally sourced materials. In this study, we explore the manufacture and characterization of lightweight bricks using Sinabung volcanic ash and Pinang fiber as an aggregate with polyester adhesive.
Background
Sinabung volcanic ash is a by-product of volcanic eruptions that have been occurring in Indonesia for centuries. This ash is rich in silica and alumina, making it an ideal material for the production of lightweight bricks. Pinang fiber, on the other hand, is a natural fiber obtained from the Pinang tree, which is widely available in Indonesia. Polyester resin is a common adhesive used in the production of composite materials.
Methodology and Testing
The tests carried out in this study include physical and mechanical analysis to determine the characteristics of the lightweight brick produced. Some of the parameters tested include:
- Density: The resulting density value ranges from 1,6127 to 1,5204 g/cm³.
- Water absorption: The measured water absorption ranges from 0.253% to 2.181%.
- Porosity: The test results showed the porosity in the range of 0.408% to 3.520%.
- Strong impact: The impact strength value ranges from 3294 to 14,918 J/m².
- Flexible strength: The measured flexural strength ranges from 9,424 to 31,048 MPA.
- Tensile strength: The resulting tensile strength ranges from 4.066 to 16,065 MPa.
Analysis of Results
The results showed that the addition of Pinang fiber had a significant influence on the physical and mechanical properties of lightweight bricks. Increasing the number of fiber tends to reduce the density of brick, which means the resulting brick is lighter. However, this increase in fiber also increases water absorption and porosity, which can have an impact on the resistance of bricks to water.
Tensile strength also increases with the addition of Pinang fiber. It can be interpreted that the fiber of Pinang function as a strengthening of the concrete matrix, increasing tensile strength and lightweight brick flexibility.
Discussion
The use of Sinabung volcanic ash and Pinang fiber as an aggregate with polyester adhesive shows promising results in the production of lightweight bricks. The addition of Pinang fiber not only reduces the density of the brick but also increases its tensile strength and flexibility. This study opens opportunities to explore the use of other alternative materials in making brick and other construction materials in the future.
Conclusion
Making light bricks using volcanic ash and Pinang fiber, which is united with polyester resin, showing promising results. Variations in the composition carried out in this study not only succeeded in producing lightweight bricks with good characteristics but also providing added value from the use of environmentally friendly local materials.
Recommendations
Further development of this lightweight brick can be utilized in the construction industry, especially in applications that require light but strong building materials. This study opens opportunities to explore the use of other alternative materials in making brick and other construction materials in the future.
Future Work
Future studies can focus on the optimization of the composition of lightweight bricks using Sinabung volcanic ash and Pinang fiber. Additionally, the use of other natural fibers and adhesives can be explored to further improve the properties of lightweight bricks.
Limitations
This study has some limitations, including the use of a limited number of samples and the lack of long-term testing. Future studies should aim to address these limitations and provide more comprehensive data on the properties of lightweight bricks.
Conclusion
In conclusion, this study demonstrates the potential of using Sinabung volcanic ash and Pinang fiber as an aggregate with polyester adhesive in the production of lightweight bricks. The results show that the addition of Pinang fiber can improve the tensile strength and flexibility of lightweight bricks, while reducing their density. This study opens opportunities to explore the use of other alternative materials in making brick and other construction materials in the future.
